Tsananguro yeSPCC inotonhora yakakungurutswa simbi mamakisi

1 tsananguro yezita
SPCCpakutanga yaive chiyero cheJapan (JIS) "kushandiswa kwese kweinotonhora yakakungurutswa kabhoni simbi sheetuye strip" zita resimbi, iye zvino nyika dzakawanda kana mabhizinesi anoshandiswa zvakananga kuratidza kugadzirwa kwavo kwesimbi yakafanana. Cherechedza: magiredhi akafanana ndeeSPCD (inotonhora-yakakungurutswa kabhoni simbi sheet uye tambo yekutsikisa), SPCE (inotonhora-yakakungurutswa kabhoni simbi sheet uye tambo yekudhirowa kwakadzika), SPCCK\SPCCCE, etc. (special steel for TV sets), SPCC4D\SPCC8D, etc. (hard steel, inoshandiswa marimu ebhasikoro, etc.), zvichiteerana, pazviitiko zvakasiyana.

2 Zvikamu
Japanese simbi (JIS dzakatevedzana) ari mugiredhi zvakajairika structural simbi kunyanya rine zvikamu zvitatu chikamu chokutanga zvinhu, akadai: S (Steel) kuti simbi, F (Ferrum) kuti simbi; chikamu chechipiri chezvimiro zvakasiyana, marudzi, uye kushandiswa, zvakadai seP (Plate) iyo ndiro, T (Tube) iyo chubhu, K (Kogu) iyo chombo; chikamu chetatu chehunhu hwenhamba, kazhinji kacho simba rekushomeka. Kazhinji kacho simba rekuita zvishoma. Zvakadai se: SS400 - yekutanga S yakataura simbi (Simbi), yechipiri S yakati "chimiro" (Chimiro), 400 kune yakaderera muganho wekusimba kwesimba re400MPa, iyo yakazara tensile simba re400MPa kune general Structural simbi ine tensile. simba re400MPa.

Supplementary: SPCC - inotonhora yakakungurutswa kabhoni simbi pepa uye tambo yekushandiswa kwese, yakaenzana neChina Q195-215A giredhi. Vara rechitatu C ichidimbu cheKutonhora. Inoda kuve nechokwadi chekuti bvunzo dzekusimba, mukupera kwegiredhi pamwe neT yeSPCCT.

3 simbi kupatsanura
yeJapaninotonhora yakakungurutswa kabhoni simbi ndiromagiredhi anoshanda: SPCC, SPCD, SPCE zviratidzo: S - simbi (Simbi), P - ndiro (Plate), C - inotonhora yakakungurutswa (inotonhora), yechina C - yakajairika (yakajairwa), D - kutsika giredhi (Dhiza), E - yakadzika yekudhirowa giredhi (Elongation)

Mamiriro ekurapa kupisa: A-Annealed, S-Annealed + Flat, 8-(1/8) yakaoma, 4-(1/4) yakaoma, 2-(1/2) yakaoma, 1-yakaoma.

Kudhirowa danho rekuita: ZF- yekubaya zvikamu zvine kudhirowa kwakanyanya, HF- yekubaya zvikamu zvine kudhirowa kwakanyanya, F- yekubaya zvikamu zvine kudhirowa kwakaoma.

Surface Finishing Status: D - Dull (mipumburu yakagadziridzwa nemuchina wekukuya uye wobva wapfurwa peened), B - Bright Surface (mipumburu yakagadziriswa nemuchina wekukuya).

Unhu hwepamusoro: FC-yepamusoro yekupedzisa nzvimbo, FB-yepamusoro yekupedzisa nzvimbo. Mamiriro ezvinhu, mamiriro ekupedzisa kwepamusoro, dhizaini yemhando yepamusoro, giredhi rekudhirowa (yeSPCE chete), kutsanangurwa kwechigadzirwa uye saizi, kurongeka kweprofile (ukobvu uye / kana hupamhi, kureba, kusaenzana).
